Default values of fraction of non-renewable biomass

The CDM Executive Board, at its ninetieth meeting, considered the recommendations of the SSC WG in relation to the parameter fraction of non-renewable biomass (fNRB) included in methodologies AMS-I.E and AMS-II.G and agreed that:

(a) The default country-specific fNRB values already approved by the Board shall expire five years from the date of their approval;

(b) In cases where Designated National Authorities (DNA) decide to propose a renewal with an update to the fNRB values, they shall follow the “Procedure: Development, revision, clarification and update of standardized baselines” (standardized baseline procedures), including for the requirement related to the period of validity of the fNRB value;

(c) The SSC WG should initiate work to propose a revision to the method for the top down development of fNRB values for consideration by the Board. Where a DNA has made a request for the top down development of fNRB values in accordance with the standardized baseline procedures, the secretariat should, after approval by the Board, initiate the work.

The table below lists the countries where designated national authorities (DNAs) have indicated their acceptance of the proposed default values of fNRB and the expiry date of the values.
